Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets, in particular to a switch cabinet. Background Art

[0002] Switch cabinets are widely used in power systems. As an electrical device, various electrical components are installed on the beams inside the switch cabinet, mainly used in power generation, transmission, and distribution. Since the electrical components in the switch cabinet are numerous and densely packed, and the cabinet door is normally closed after installation, a large amount of heat is generated inside the cabinet. At this time, timely heat dissipation is required to ensure the normal use of the electrical components inside the cabinet. A common heat dissipation method in existing switch cabinets is to open heat dissipation holes on the side walls of the cabinet. This method makes it easy for small animals or other debris to enter, affecting the safety of the switch cabinet. Of course, there are also protective nets added to the heat dissipation holes, but this structure is inconvenient to clean thoroughly after long-term use; or the heat dissipation net is directly installed at the heat dissipation port on the outside of the cabinet with screws or other fasteners. This structure has certain hidden dangers and is easy to be opened by non-staff. Utility Model Content

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] As shown in the figure, a switch cabinet includes a cabinet body 1, with heat dissipation windows 11 formed on both inner side walls of the cabinet body 1. A square mounting frame 2 is fixedly attached to the inner side walls of the cabinet body 1 at a position corresponding to each heat dissipation window 11. A heat dissipation net 3 is plugged into and fixed to each mounting frame 2. A ridge 21 is fixedly attached to the upper and lower sides of the mounting frame 2. A frame 4 is fixedly attached to the heat dissipation net 3. The upper and lower sides of the frame 4 are provided with hook-shaped clips 41 extending outwardly, and the clips 41 are clipped into the corresponding clips 21. In this embodiment, the heat dissipation net 3 is installed inside the cabinet body 1 to prevent unauthorized disassembly from outside the cabinet body 1 by non-staff members. The heat dissipation net 3 is configured to be plugged in and fixed, making it easy to disassemble and clean after long-term use and avoiding affecting the heat dissipation inside the cabinet body 1. Furthermore, mounting frames 2 are provided inside the cabinet body 1 at positions corresponding to the heat dissipation windows 11, and the heat dissipation net 3 is mounted on the mounting frames 2. This facilitates the disassembly and removal of the heat dissipation net 3, without being affected by the position of the door (not shown) on the front side of the cabinet body 1. In this embodiment, the heat dissipation net 3 moves from the front side of the installation frame 2 to the rear side and is installed by sliding the clamping strip 41 on the protruding strip 21. This arrangement is convenient for disassembly and assembly, and is not easily disassembled by people outside the cabinet 1.

[0023] The mounting frame 2 and the ridge 21 are integrally formed, and the top of the ridge 21 is configured as a curved surface. The shape and size of the slot 42 at the bottom of the clip 41 are consistent with those of the ridge 21. In this embodiment, the top of the ridge 21 is configured as a curved surface to facilitate insertion into the slot 42 of the clip 41 and reduce friction.

[0024] Fixing blocks 43 are secured to both the upper and lower front portions of the frame 4. Countersunk holes 44 are defined in these fixing blocks 43, and threaded holes 22 are defined on the front side of the mounting frame 2 corresponding to each countersunk hole 44. Fixing blocks 43 are secured to the front side of the mounting frame 2 via screws engaging the countersunk holes 44 and the threaded holes 22. In this embodiment, fixing blocks 43 serve to position the heat sink 3, ensuring that it completely covers the heat dissipation window 11. Furthermore, they secure the heat sink 3 to the mounting frame 2, preventing unauthorized personnel from removing the heat sink 3 from outside the cabinet 1.

[0025] A handle 45 is fixedly connected to the middle of the front side of the frame 4 to facilitate pushing and pulling the heat dissipation net 3.

[0026] The mounting frame 2 is welded and fixed on the inner side of the cabinet 1 .

[0027] The working process of this embodiment is as follows:

[0028] The heat sink 3 moves backward from the front of the mounting frame 2, with the clip 41 slidingly engaging the protrusion 21, which then engages the slot 42, guiding and limiting the heat sink 3 during installation. After the heat sink 3 completely covers the heat dissipation window 11, the fixing block 43 abuts the front of the mounting frame 2, and the fixing block 43 and the mounting frame 2 are fixed together with screws, thus securing the heat sink 3 in place. To remove the heat sink 3 for cleaning after extended use, simply remove the screws and pull the handle 45 outward to remove the heat sink 3.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
